Cement is a material used for construction purposes. It is used for the purpose of binding other materials together. It can be categorized into hydraulic cement and non-hydraulic cement. The setting of hydraulic cement requires water as a hydration reaction which is involved in its hardening. The most common example of hydraulic cement is Portland cement which is the key ingredient in concrete and mortar. Non-hydraulic cement undergoes carbonation when it interacts with the carbon dioxide present in the air. It becomes resistant to any deterioration caused by chemical agents. Polymer cement is also a common category of cement. They are derived from organic chemicals that have the ability to polymerize. Polymer cement is preferred for its tensile strength and water resistance. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of cement. It presents researches and studies performed by experts across the globe. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in this area at various levels.
